I wonder which cross-platform software or services you are using for remote screen sharing sessions, if any?
[...] A typical situation would be: I use Debian 8 and I want to share my screen with a client or partner running Windows or Mac to demonstrate something.
Does anyone have any experience, suggestions, advices in this regards?
Probably not helpful, but... I only needed to share charcell (not GUI), so I just used GNU Screen. It has some basic access control features, but it was easier to just have both workers log into the same account, and trust the other guy not to mash the keyboard at the wrong time. :P For chatting I either just used write/talk to a second Screen tab, or installed ircd on 127.0.0.1 and had each user run irssi to that. If you don't already know GNU Screen, try tmux first.
